广角反射折射地震资料是较特殊的一类资料,其明显特点是:记录长,排列长,多种波场混合、反射能量强。用其进行深层勘探,可以大幅度提高深层地震资料的品质。本文从理论推导和模型试算上给出了反射资料不同于常规采集资料的处理方法,即反射波和折射波分离技术,大偏移距动校正叠加及正反演技术。尤其值得一提的是将这种海上的方法首次应用到了辽河地区陆上资料,并较好的提高了深层资料的品质。在浅层资料中大面积火山岩屏蔽区也取得较好效果。
Wide-angle refraction seismic data is a special kind of information, its obvious characteristics are: record length, long arrangement, a variety of wave field mixing, strong reflection energy. With its deep exploration, can greatly improve the quality of deep seismic data. In this paper, we deduced the processing methods of the reflected data different from the conventional data collection from the theoretical derivation and the model trial calculation, that is, the reflected wave and refracted wave separation technology, the large offset dynamic correction superposition and the inverse inversion technology. Particularly worth mentioning is the first application of this method at sea to the Liaohe land data, and better improve the quality of deep data. Large-scale volcanic shield in shallow data also achieved good results.
